Yo, Richard...

Resonating stringed instruments can be very loud... Back when I was participating in weekly jams at Archie Edwards Barber Shop there was one particular player who had a metal bodied National resonator and it was louder than all the rest of the acoustic guitars combined... I remember Mike Baytop stopping a jam and asking it's owner to play softer... The owner was embarrassed but never again played it hard... He got it...
